Now just added to the product section is the Amazon & the iOffer VCC’s! Whether you are selling on iOffer or on Amazon, both sites require some sort of credit card for validation in order to become a seller. For many, this may be hard as obtaining a credit card can be difficult or they simply do not want to add their card for personal reasons. Whatever the case may be, virtual credit cards or VCCs for short can help solve those issues by protecting personal, sensitive information & altogether avoiding the hassle in applying for one.
